Picking up where the VZ-1 HD left off, IPEVO’s iZiggy HD document camera breaks new ground for classroom use. It can not only capture 2,592 by 1,944 images with its 5-megapixel sensor, but can wirelessly transmit them to an iPad or PC. The material can be marked up and annotated using the company’s included software and its articulated arm lets the lens get in close to the original. At $159, it puts other doc cams to shame.
